Good idea to give them some raw carrot to chew on as veg grown below ground is a stool hardener and veg grown above a stool softener. My dogs love all kinds of fresh veg but I don't give broccolli and go easy with cabbage as it makes them very windy, so not that good for them.

Thanks so much everyone, we've got a lot more to go on now! Will def get the vet to test for the things mentioned and try the boys on Probiotics. Brilliant advice, thanks again!

My dogs are fed Burns and i find that if i mistake the amount of food i give them(over feed) then they get runny , as soon as they are on the right amount all is ok,

Bisto has always had a bit of a sensitive tummy, but since switching to JWB (no chicken) he's been fine, up till today when we started the switch to adult food from junior. Hmmmmmmm have to keep an eye on this. I have read somewhere that most food allergies in dogs is down to chicken and/or beef!!! Don't quote me on that tho as I can't remember where I read it. I would suggest switching to something with no chicken, and try cutting out their treats as it maybe them.

I thought most allergies were down to grain, particularly wheat.
